The present invention improves the cosmetic appearance of skin by
controllably heating a superficial layer of skin thereby inducing acute
tissue contraction or shrinkage and a wound response leading to the
production of biomolecules, all of which result in improved cosmesis. The
invention incorporates a source of radiofrequency electrical energy
coupled to coil, with requisite impedance matching network, thereby
resulting in the production of an alternating magnetic field. When tissue
is brought into proximity of the alternating magnetic field, inductive
heating of the tissue results as a consequence of either or both of
dipole formation and oscillation, and eddy current formation. Optionally,
cooling is provided to remove heat from the coil, the source of
radiofrequency electrical energy, or the surface of the skin alone or in
combination. The invention exhibits the significant benefits of, among
other things, being non-invasive, not requiring electrical contact with
the body of the subject, and providing controllable heating only to a
thin layer of tissue.
